Granita is such a refreshing and simple recipe, it should be part of every backyard barbecue menu. This one highlights that icon of warm weather - watermelon. In this recipe I suggest a slightly fancier version with a garnish of candied citrus peel and port wine, but it would be equally satisfying with just a few pieces of fresh watermelon and a sprig of mint.

Stir the water and sugar together in a medium saucepan. Bring to a boil over medium heat, remove from the heat and let cool to room temperature.
